manufacturer's recommendation:
powering orbit directly from the computer can sometimes cause interference with the operation of the scanner or the computer. not all computers supply the same current through the keyboard port, explaining why a scanner will work on one computer and not another. metrologic recommends using an external power supply. for additional information contact a metrologic customer service representative.
1、to maintain compliance with applicable standards, all circuits connected to the scanner must meet the requirements for selv (safety extra low voltage) according to en 60950.
2、to maintain compliance with standard csa c22.2 no. 950/ul 1950 and norm en 60950, the power source should meet applicable performance requirements for a limited power source.
